Well, worst thing that happend luckily only ones is, that after you found the anime you've been hunting for long, you watch it only to see that the subs are awfully every way wrong and have to go hunting all over again.

Also those young female characters that scream like they were in hentai movie are annoying. Especially when you are in a room where's other people.

And sometimes it's weird to look how some girls behave. If boys that are so young they don't know about anything of how to be with girls see that, it's more harm to their future than good.

Yes, chauvinistic animes can be also annoying for how they bring more that kind of attitude.

When an Arc(not necessarily filler) drags on FOREVER.
Those long transformations that have to be played over and over again,without any shortened version.
Characters with annoying voices.
Most 'hyper' anime characters (like Yaya from Shugo Chara)
I don't know why but when anime people cosplay it annoys me O.o

Pretty much whe people sit there and try to decide what to do next... I mean if I was in an anime and i stood there watching my opponent think to themselves I would attack. A also hate it in some romances where the girl or guy is caught between deciding on two or more people. It gets really annoying and boring...

This is going to seem like I don't enjoy anime at all xD but here are my pep peeves about anime:

1. Those long annoying flashback/thought-processes in a middle of a battle or fight scene. Does time stop for like 5-10 minutes just so they can have a revelation? I wanna see some blood and guns goddammit, not your horrible upbringing

2. How the all characters say each other's name every 5 flippin seconds for no good reason

3. When someone does a kick-ass move, another character shouts out what they're doing as if we, the audience, don't get whats going on and are so unintelligent that we need a freaking play-by-play

4. The gasping! What is with all the freaking gasping!?

5. All the traps/fags in shojo manga/anime, especially when they have no relevence to the plot. I'm a yaoi fan, but still! teh gheyz belong in yaoi manga/anime!

6. How the teenage boys act all nervous around girls. Your like 15! You want to see some naked chicks, its natural! I mean, its cute for like 15 minutes, but when it gets too excessive I'm like just fucking touch her already!

7. References to tentacle rape. Im not watching hentai, Im watching normal anime. I don't want to see that shit, its fucking gross! Who finds that hot anyway? If you're fapping to an octopus wrapping themselves around young girls in schoolgirl outfits, I think you need some professional help.

9. No kiss/confessions of love in a romance anime. I didn't watch a romance anime so that the love interests go through all this drama and still decide to be just friends in the end!

10. Engrish subtitles. If you don't understand English that well and can barely put a correct sentence together, then you shouldn't be fan-subbing! I hate pausing every time a new line comes up so I can try to figure out what the hell the characters are saying.

I probably have more lol but I can't remember. Hope you enjoyed my rant! ^^

1. Fillers - Who cares about extra talking? Waste of an episode and stalling.
2. Character Fights That Take TOO LONG - Sheesh, we know what might happen, but it takes forever because sometimes they talk too much.
